If I do: % cd /usr/ports/x11/nvidia-driver % make pretty-print-build-depends-list % make pretty-print-run-depends-list This port requires package(s) "gettext-0.14.5 libiconv-1.9.2_1 linux-XFree86-libs-4.3.99.902_3 linux-expat-1.95.5_3 linux-fontconfig-2.1_3 linux_base-8-8.0_6 popt-1.7 rpm-3.0.6_10" to run. There's no mention of java. I wouldn't say it definitively rules it out though. Are you sure that java wasn't left over from 4.X? One thing to try is: % pkg_info | egrep -i java javavmwrapper-2.0_4 Wrapper script for various Java Virtual Machines jdk-1.4.2p7_1 Java Development Kit 1.4.2 linux-sun-jdk-1.4.2.08_2 Sun Java Development Kit 1.4 for Linux vnc-4.1.1 Display X and Win32 desktops on remote X/Win32/Java display % pkg_info -R jdk-1.4.2p7_1 Information for jdk-1.4.2p7_1: % pkg_info -R linux-sun-jdk-1.4.2.08_2 Information for linux-sun-jdk-1.4.2.08_2: Which shows that nothing on my system positively requires java (though mozilla et al. use it). I doubt it's a browser as javac is the compiler rather than the runtime environment (which has always seemed to crash at irregular intervals for me). >>If the problem is intermittent then I would suspect the hardware (I >>know, everyone always says that, but I really have used a brand new >>server which segfaulted randomly and it really was a memory problem). >>Try building a memtest86 CD from the ports (from a different machine >>perhaps) and running it for at least several hours, though it might not >>take that long.

Memtest is dull, and stops you using your PC, but like Windows virus scans, it seems like a necessary evil in this case. --Alex
